I have a USB data traveler 8gb thumb drive. I have used it in the past and it hads 8gb of space like it says. I eventually erased everything from the drive and installed a USB version of google chrome OS just to test it out, after I did that I erased the drive again. ever ince then the drive is completed erased/formated butno matter what I do, even with the drive appearing empty, it still says that it is now a 250mb drive instead of an 8gb drive. This is really frustrating as I cannot install anything on it larger then 250mb even though it should have 8gb of space. I am using it on Windows 7. Any help is greatly appreciated. I have tried formatting is several times with no success in getting it to register as an 8gb drive instead of a 250mb drive.
